AppStore Version: Mac OS X 10.6 - 10.11. ![]() ![]() A tool that allows you to remotely access the desktop of a computer, has a long history and has been available in many shapes and forms. Not entirely surprising, plenty of free VNC Servers and VNC Clients are available for Windows and Linux, but the selection for MacOS X appears rather limited. Sure, there are a lot of VNC clients for MacOS X but hardly any of them are free, but why install yet another application when you already have a VNC Client and Server installed? In this article, we will use the build in VNC Server and VNC Client it comes with your Mac for free! A little VNC background info VNC, or Virtual Network Computing, was originally developed by the (doesn’t exist anymore) which later spun off an organization called in an attempt to keep VNC available. VNC is a graphical desktop sharing system that allows a user to remotely control another computer, by seeing the screen of that computer on their own computer and using their own keyboard and mouse to control the other computer. For remote display, simply put, VNC keeps sending screenshots to the VNC client as JPEG pictures by means of the so called protocol. The JPEG compression can be changed based on the available bandwidth – sometimes resulting in very poor image quality when bandwidth availability is very limited. Microsoft RDP is not VNC Personally I prefer, Microsofts’ Remote Desktop Protocol, but MacOS X does not support RDP as a server protocol. RDP seems more robust and the graphical display or the remote computer’s screen typically are much better. The better image quality is because RDP is “semantic”, meaning: it’s aware of controls, fonts, etc. Which means that these controls will be drawn by the client application thus sending much less data to the client application and a much cleaner display of the screen of the controlled computer. Note: You can get a so you can remotely control Windows PC’s. For VNC to work you will need a VNC Server and VNC Client. Laserjet 5 printer driver download.

B is the CLIENT computer, which is running a VNC Client application. This is the computer that will control the other computer remotely. 1 is the stream of screenshots of the desktop of the computer that is going to be remotely controlled. The screenshots are send over a network connection so that the VNC Client software can display the desktop pictures. 2 is the stream of mouse moves and key strokes from the Client, send over a netwokr connection as well, so that the server can actually execute the. VNC Server or Enabling Screen Sharing The VNC Server is the application running on the computer, or device, which screen is being shared. This can be your Mac, a Windows or Linux PC, or even an Android tablet, or iPhone (jailbreak needed to run Veency, the VNC server for iOS). The main purpose, besides login and other security gimmicks, is to provide access to the computer that is running VNC server by sending “screenshots” to the client, and to translate incoming mouse movements or keyboard strokes. MacOS X has a VNC server build in which can be ENABLED or DISABLED in the “System Preferences”. Click the icon in the upper left corner and from the menu that opens, choose “ System Preferences“.
